It should be noted, for example, that although the exemplary embodiment of the toiletis shown configured with the tankformed separately from the pedestaland later coupled to the pedestal, the tank may be integrally formed with the pedestal as a one-piece design. In other words, the toilet may be a one-piece design, a two-piece design, or have any suitable configuration. The toilet disclosed herein may have a wide variety of skirted toilet configurations, and all such configurations are intended to be encompassed herein. The following description of various toilet features is therefore intended as illustration only of one possible embodiment, and it should be understood by those reviewing the present description that similar concepts or features may be included in various other embodiments.

The tankmay include an inlet opening configured to receive water from a coupled water supply, such as from a hose (e.g., line, tube). The tankmay also include an inlet valve assembly or other device configured to control the flow of water from the water supply into the tank through the inlet opening. Within the tankmay be provided a float device for controlling the inlet valve assembly, such as by opening the valve to refill the reservoirof the tankafter an operational cycle and closing the valve when the water in the reservoirreaches a preset volume or height. The tankmay also include an outlet opening configured to transfer (e.g., conduct) the water stored in the reservoirof the tank to the pedestalupon activation of the actuator. The pedestalmay include toilet bowl. The tankmay include an outlet valve assembly or other device configured to control the flow of water from the tank into the pedestalthrough the outlet opening.

The pedestal(or base) of the toiletmay include a wallhaving any suitable shape that is configured to form a bowlhaving an opening formed by an upper rim at the top of the opening. The pedestalmay also be configured to include a plurality of walls having varying shapes that together form a bowl having an opening formed by a rim. The wallof the pedestal may extend downward and/or rearward from the bowlto form a lower portionconfigured to support the pedestaland the toilet. The lower portionmay be formed by the end (e.g., lower rim) of the wall, or may include a member that extends generally in a horizontal plane from one or more than one end of the wall. The pedestalmay also include a top memberthat extends between two sides of the wall(or between two opposing walls) and is provided rearward (or behind) the bowl, wherein the top memberforms a plateau for supporting the tank, such as the bottom surface of the reservoirof the tank. The top membermay include an inlet opening that may be aligned with the outlet opening of the tank, such as when the tankis coupled to (or resting above) the pedestal, wherein water is selectively transferred (e.g., conducted) from the tankthrough the outlet opening of the tank to the pedestalthrough the inlet opening of the pedestal, when the toilet is activated through the actuator. The outlet valve assembly may control the flow of water from the tank to the pedestal. The toilet may also include a gasket or seal that is provided between the tankand the pedestalto prohibit leaking. For example, a gasket may be provided between the outlet opening of the tank and the inlet opening of the pedestal to prohibit leaking between the tank and the pedestal.

The plateau formed by the top memberof the pedestalmay also provide for coupling of the seat assemblyto the pedestalof the toilet. For example, the top membermay include one or more than one opening, wherein each opening is configured to receive a fastening device (e.g., bolt, screw, etc.) to couple (e.g., attach) the seat assemblyto the top memberof the pedestal. As another example, the top membermay include one or more than one fastening device (e.g., bolts, recessed nuts, etc.) integrally formed therein (i.e., already provided connected or coupled to the pedestal), wherein the fastening device may be used to couple or secure at least a portion of the seat assemblyto the pedestal.

The bowlof the pedestalmay be configured to include a receptacle (e.g., sump) and an outlet opening, wherein the water and waste is collected in the receptacle until being removed through the outlet opening, such as upon activation of the actuator. The pedestalmay also include a pedestal internal passageway, such as a trapway, that connects the outlet opening or discharge outlet of the bowlto a drain or soil pipe. The passageway, or trapway, generally includes a first portion, a second portion, and a weir separating the first and second portions. The first portion of the passageway may extend from the outlet opening of the bowlat an upwardly oblique angle to the weir. The second portion of the passageway may extend from the weir downwardly to the exiting device, such as the drain or soil pipe.

Between operational cycles (e.g., flush cycles) of the toilet, the water (and waste) is collected in the first portion of the trapway (in addition to the receptacle of the bowl), such that the weir prohibits the water from passing past the weir and into the second portion of the trapway. A flushing cycle may begin upon activation of the actuator. Upon activation of the actuator, additional water (e.g., fresh water and or grey water) may be discharged into the bowlof the pedestal, resulting in the flushing action and waste removal through the soil pipe. The flushing cycle may include generation of a siphon to assist the flushing action and waste removal.

The apparatusmay include a mounting bracket, an offset arm, a hinge, and a lift portionhaving a lift frameand lift arms. The apparatusmay be configured to lift a user via the lift armsand rotate and/or translate the user to position on a toilet. The apparatusmay optionally be mounted to a wall proximate to a toilet. In another example, the apparatus may be secured to a column or stand configured to support the apparatuslocated proximate to a toilet.

The mounting bracketmay be configured to mount or secure the apparatusto a wall proximate to a toilet. For example, the mounting bracketmay mount or secure the apparatusto wall located behind a toilet, such that the apparatusis located above the toilet. In some examples, the mounting bracketmay mount or secure the apparatusto a wall located behind a toilet such that the apparatusis offset from the toilet (e.g., such that only a portion of the apparatusis disposed above the toilet). The mounting bracketmay be composed of metal, plastic, wood or any combination thereof and may be configured to receive one or more fasteners for mounting or securing the mounting bracket to the wall. The mounting bracketmay have a shape allowing fasteners to be inserted through the mounting bracketinto multiple different mounting points (e.g., studs) in the wall.

The offset armmay extend outward from the mounting bracketand is configured to support the hingeand lifting portion. During use, the offset arm is configured to support the weight of an individual in addition to the hingeand lifting portion. In some examples, the offset armmay be integrally formed with the mounting bracket. In other examples, an end of the offset armmay be fixed, connected, or attached to the mounting bracket.

The lift portionis configured to rotate via the hingerelative to the offset armand/or the mounting bracket. The lift framemay be coupled or connected to the hinge. In some examples, the hingeor a portion of the hingemay be integrally formed with the lift frame.

The one or more lift armsmay be configured to lift or raise a user. In some examples, each of the lift armsmay be configured to be held by a user and held on to during lifting and/or movement of the user. In other examples, each of the lift armsmay be configured to be positioned in an armpit of the user in order to lift and/or move the user. After the lifting armshave been positioned in the armpits of a user or the user has gripped the lifting arms, the offset arm may lift a user. One or more electric motors may be configured to lift the offset arm. In some examples, the offset armmay be begin and remain in a horizontal position while the user is lifted. Specifically, the offset armmay translate vertically (e.g., along the mounting bracket) while remaining horizontal. In other examples, an end of the offset armconnected to the mounting bracketmay remain in the same position and an electric motor may be configured to lift a distal end of the offset arm; in a lifted position the offset armmay be disposed at an angle with respect to a horizontal axis.

After a user has been lifted, the apparatusmay rotate and/or translate so that a user may be positioned on a toilet. In some examples, as illustrated in, the apparatusmay include two lift arms. In other examples, the apparatusmay include three or more arms. The lifting armsmay be secured or connected to the lift frame. For example, one lift armmay be secured to each end of the lift frame. In some examples, the lift armsmay be configured to move along the length of the lift frame. For examples, the lift armsmay move closer to one another to accommodate a smaller user and/or further away from one another to accommodate a larger user.

Accordingly, the apparatusmay be configured to lift a user from seated position (e.g., in a wheel chair) and move or transport them to a toilet. In other examples, an apparatus for moving a user may be mounted on a wall and lift a user while translating along a surface of the wall without rotating. Such an apparatus may include, for example, a track disposed on the wall at an angle with respect to a horizontal axis and the apparats may translate along the track to lift or move a user to a toilet.

Referring to, an adjustable height toilet seatis illustrated. A position of the toilet seatmay be adjusted to improve user comfort and experience for users of different heights. The toilet seatincludes a top surfaceand one or more lifts. A hinge or hinge assembly may secure the toilet seatto a base (e.g.,) of the toilet. The one or more liftsmay be secured or attached to the bottom surfaceof the seat. The one or more liftsmay be configured to selectively adjust the height of the seat, specifically, the top surfaceof the seat. The one or more liftsmay adjust the height of the seat without having to change a hinge or hinge assembly used to secure the seatto the base of the toilet.

Each of the one or more liftsmay include one or more telescoping members. For example, as illustrated in, the each of the one or more liftsmay include three telescoping members,, and. The shape of the telescoping member,,may vary. For example, as illustrated in, the telescoping members,,may have a circular or cylindrical shape. In other examples, the telescoping members,,may have a rectangular shape. Each of the telescoping members may have a different cross sectional area so that the telescoping members may fit or nest inside one another. For example, the telescoping membermay have a larger cross sectional area than the telescoping memberso that the telescoping membermay fit or nest into the telescoping member. Additionally, the telescoping membermay have a larger cross sectional area than the telescoping memberso that the telescoping membermay fit or nest into the telescoping member.

The telescoping members,,may be selectively arranged to either reside or nest inside other telescoping members,,or protrude from other telescoping members,,. When the telescoping members,,extend from other telescoping members, as opposed to nesting within them, a total length of the nesting members,,and thus a height of the liftmay be increased. A locking mechanism may be used to maintain a position of each of the telescoping members relative to one another. For example, a clamp, or a twisting lock may be used to maintain a position of the telescoping members,,relative to one another. Accordingly, the height of a top surfaceof the seat may be adjusted by changing the orientation of the telescoping members,,and locking a position of the telescoping members,,relative to one another.

As illustrated in, the liftsof the toilet seat include three telescoping members,,; however, the present disclosure is not limited thereto, and additional telescoping members may be included. In other examples, one or more stackable toilet seats may be used to increase the height at which a user sits. A bottom surface of a stackable toilet seat may be configured to enclose or surround a top surface or a portion of a top surface of the stackable seat so that the stackable seats may be placed on top of one another without moving. One or more grooves and protrusions may be used to secure a position of the stackable seats. A user may sit on a top surface of the top seat.

Referring to, a toiletincluding a ledgeis illustrated. The ledgemay allow a small user (e.g., a child) to more easily get on and/or off of the toilet. Additionally, a user may place their feet on the ledgeto achieve a more comfortable or natural posture while using the toilet.

The ledgemay extend from a pedestal or baseof the toilet. The basemay be the same as the base or pedestaldescribed above with respect to. In some examples, the ledgemay be integrally formed with the base. In some examples, the ledgemay be over onto the base. In other examples, the ledge may be attached or connected to the base. In some examples, the ledgemay be comprised of vitreous china and/or polymeric material. The ledgemay be comprised of the same material as the base. In other examples, the ledgemay be comprised of metal, plastic, or a combination thereof. As illustrated in, the toiletincludes one ledge; however, the present disclosure is not limited thereto. For example, two or more ledgesmay be included. In one example, two or more ledgesmay be included to provide multiple steps allowing a user to reach a seat of the toilet.

In some examples, the ledgemay be selectively moved between an extended position and a collapsed position. For example, a hinge may rotatably connect one end of the ledgeto the baseand a support arm may extend upward and outward diagonally to support a second end of the ledge. Selectively moving the ledgebetween an extend position and a collapsed position may allow the ledgeto be stored when not in use.

Referring to, a toiletincluding a seathaving an inclined top surfaceis illustrated. As illustrated in, the top surfaceat a back portionof the seatmay be located above the top surfaceat a front portionof the seat. The inclined top surfaceof the seat may be configured to comfortably accommodate users of various heights. For example, comfort for a relatively short user may be improved when sitting on the relatively low top surfacetoward a front portionof the seat. Conversely, comfort for a relatively tall individual may be improved when sitting on the relatively high top surfacetoward a back portionof the seat.

As illustrated in, the toiletincludes a baseincluding a bowland a rimdisposed around a top of the bowl. The toiletfurther includes a seatrotatably coupled to the rimvia hinge. The basemay be the same as pedestal or baseas described above with respect to. The bowlmay be the same as bowldescribed above with respect to. The rimmay define an opening of the bowl.

The hingemay rotatably couple the seatto the rimof the toilet. In some examples, the toiletmay further include a cover. The hingemay rotatably couple a cover to the rimof the toilet.

The seatincludes a top surfaceconfigured to support a user and a bottom surfaceopposite the top surface. The seatmay be comprised of plastics, such as polypropylene (PP), polyethylene, polycarbonate, or other similar materials. In other examples, the seat may be comprised of other materials. Then the seatis in a lowermost position, the top surfaceof the seat is disposed at an incline. The top surfacemay be disposed at an incline such that a top surfaceof the seat at a back portionof the seatmay be disposed above the top surfaceat a front portion of the seat. When the seatis in a lowermost position, the bottom surfaceof the seat may be supported by the rim. One or more elements or components, for example bumpers may be disposed between the bottom surfaceof the seatand the rimwhile a bottom surfaceof the seat is supported by the rim.

In some examples, the rimof the toiletmay be disposed along or parallel to a horizontal axis. When the rimof the toiletis disposed along or parallel to a horizontal axis, the bottom surfaceof the seatmay also be disposed along or parallel to a horizontal axis when the seat is in a lowermost position. In these examples, a thickness of the seatmay vary to achieve an incline along the top surfaceof the seat. Specifically, a distance or height of the seatbetween the top surfaceand the bottom surfacemay increase along the seatfrom a front or front portionof the seatto the back or back portionof the seat.

In other examples, the rimof the toiletmay be disposed at an incline. In these examples, a thickness of the seatmay be uniform and the top surfaceand bottom surfaceof the seatmay be parallel to the rimwhen the seatis in a lowermost position. Specifically, the rimmay support the bottom surfaceof the seat such that both the bottom surfaceand top surfaceof the seat are disposed at the same inclination as the rim. The baseof the toiletmay be manufactured to include a rimdisposed at an incline.

In some examples, an inclination angle between the top surfaceof the seatin a lowermost position and a horizontal axis may be between 0 degrees and 30 degrees. In other examples, an inclination angle between the top surfaceof the seatin a lower most position and a horizontal axis may be between 5 degrees and 25 degrees. In yet other examples, an inclination angle between the top surfaceof the seatin a lower most position and a horizontal axis may be between 10 degrees and 20 degrees.

In examples where the rimis disposed at an incline, an inclination angle between the rimand a horizontal axis may be between 0 degrees and 30 degrees. In other examples, an inclination angle between the rimand a horizontal axis may be between 5 degrees and 25 degrees. In yet other examples, an inclination angle between the rim and a horizontal axis may be between 10 degrees and 20 degrees.

The top surfaceof the seatmay not be planar. For example, an outer edge of the seatmay be disposed above an inner edge of the seat. The outer edge of the seatmay be an edge furthest from the bowland the inner edge of the seat may be an edge closest to the bowl. Accordingly, in some examples when it is stated that a top surfaceat a back portionof the seatis above the top surfaceat a front portionof the seat, the entire top surfaceat a back portionof the seat may not be above the entire top surfaceat a front portionof the seat, but rather an average elevation or height of the top surfaceat a back portionmay be greater than an average height or elevation of the top surface at a front portion. In other examples, the entire top surfaceat a back portionof the seatmay be located above the entire top surfaceat a front portionof the seat.

Referring generally to, devices, systems, and methods for reducing splashing or splash back that may occur during use of a toilet are illustrated. The following devices, systems, and methods may improve toilet cleanliness and the cleanliness of surfaces proximate to a toilet by reducing splash back. In some examples, the following devices, systems, methods may reduce the frequency with which the toilet and/or surfaces proximate to the toilet need to be cleaned.

Referring to, a toiletincluding a dampeneris illustrated. The dampenermay be disposed within a bowl structureand be comprised of a softer material than the bowl structure. The term “softer” may be defined as a lower hardness as measured by a durometer (e.g., Shore durometer). The dampenermay reduce splash back occurring when the toiletis used by softening a portion of the bowl inner surface. In some examples, the toiletmay include two or more dampeners. The dampenermay be attached to or integrally formed with the bowl structure inner surface.

The toiletmay include a basehaving a bowl structure. The bowl structuremay include a bowl structure inner surface. The toilet may further include a dampenerhaving a dampener inner surface, a bowl inner surfacedefined by the bowl structure inner surfaceand the dampener inner surface, and a discharge outlet. The basemay be the same as the pedestal or baseas described above with respect to.

The bowl structuremay include one or more walls (e.g., wall) forming a bowl within the baseof the toilet. The bowl structuremay include a bowl structure inner surface. The bowl structure inner surfacemay be an exposed surface of the bowl structure on an interior of the base. In some examples, the bowl structure inner surfacemay include one or more indentations or recesses. Each of the indentations or recesses may be configured to receive a dampener. In some examples, the bowl structureand/or basemay be comprised of vitreous china.

In some examples, a toilet (e.g., toilet) may include one or more dampeners. The one or more dampenersmay be integrally formed with the baseand/or the bowl structure. For example, the dampenermay be over molded on to the baseand/or the bowl structure. In other examples, the one or more dampenersmay be formed separately from baseand/or bowl structureand attached to the bowl structureby the manufacturer of the toilet. However, it is also envisioned that one or more dampenersmay be sold as after-market add-on products capable of being installed on a toilet by a user or technician. The dampenermay be configured to be attached to the bowl structure inner surface.

The dampenermay be comprised of a material that is softer than a material comprising the bowl structure. For example, the dampenermay have a lower hardness rating on the Mohs hardness scale than the bowl structure. The dampenermay be comprised of a polymer. For example, the dampenermay be comprised of silicone. The size and/or shape of the dampener may vary. For example, the dampener may have a cylindrical shape, an elliptic cylinder shape, a cuboid shape, or the like.

The dampenermay be integrally formed with the bowl structure, attached to the bowl structure, or configured to be attached to the bowl structure. The dampenermay be attached to the bowl structureusing an adhesive or a coupling device. The coupling device may include a snap fit connector, an anchor, or a hook.

The dampener may include a dampener inner surface. The dampener inner surfacemay be an exposed surface of the dampenerwithin the bowl structurewhen the dampeneris integrally formed with or attached to the bowl structure. The dampener inner surfacemay be coextensive with the bowl structure inner surface. The shape of dampener inner surfacemay vary. For example, the dampener inner surfacemay have a circular shape, elliptic shape, rectangular shape, or the like. Other shapes of the dampener inner surfaceare possible. Additionally, a thickness of the dampenermay vary. Specifically, a distance from the dampener inner surfaceto a back surface of the dampenermay vary.

In some examples, the toilet may include two or more dampeners. The position of the dampenerin the bowl structuremay vary. For example, one or more dampenersmay be located on a front portion of the bowl structure. For example, one or more dampenersmay be located between a front of the bowl structureand the discharge outlet. In other examples, one or more dampeners may be located in a back portion of the bowl structure. For example, one or more dampenersmay be located between the back of the bowl structureand the discharge outlet. In other examples, one or more dampenersmay be located on either side of the bowl structure. For example, one or more dampenersmay be located on either the left side or the right side of the discharge outlet. One or more dampenersmay be located in different positions. For example, one or more dampenersmay be located on a front portion of the bowl structureand one or more dampenersmay be located on and a back portion of the bowl structure.

Referring to, an adjustable fill toiletis illustrated. The toiletmay be configured to selectively increase a water line or water level in the bowlof the toilet without initiating a siphon or flushing sequence of the toilet. In some examples, after a flush cycle the toiletmay have a relatively low or reduced waterline or head. The relatively low head may advantageously reduce splashing during toilet use; however, having a relatively low head may reduce the waste removal performance of the toilet. Accordingly, the toiletmay selectively increase the waterline or head in the toilet to selectively attain the advantages of a toilet having a relatively low head or the advantages of a toilet having a relatively high head.

The toiletincludes a basehaving a bowl, a primary reservoir, a flush valve, a secondary reservoir, and an adjustment valve. In some examples, the toiletmay additionally include an actuator. In other examples, the toiletmay additionally include a user input device, a controller, and/or a seat. The baseof the toiletmay be the same as the base or pedestaldescribed above with respect to. The bowlmay be the same as the bowldescribed above with respect to.
